OEM vs. Aftermarket Parts: What Are You Really Paying For?
OEM parts are made by the original equipment manufacturer and sold through dealer networks. Aftermarket parts are made by independent companies. When engineered to the same standards, they can match OEM performance at a significant discount.
WHAT ARE AFTERMARKET PARTS?
Aftermarket parts are replacement components manufactured by independent companies. Leading independent manufacturers like Kooima Ag specialize in aftermarket parts. They can match or exceed OEM specifications at a lower cost.
HOW ARE AFTERMARKET PARTS MORE AFFORDABLE THAN OEM?
OEMs have to work with a supplier, a factory, a distributor, and a network of dealers. Aftermarket parts cost less not as a testament to their quality, but because of a leaner supply chain. They don't have the same overhead costs so they can pass those savings onto you.
Kooima Ag passes savings to customers by:
Operating under one roof. Manufacturing, warehousing, sales, and shipping all happen in a single facility; eliminating the middlemen.
In-house manufacturing. With manufacturing steps away from our team of engineers, refinement happens faster and cheaper.
Prime location. Situated in the heart of the Midwest, local and realistic testing sites are all around us.
Great relationships. Kooima Ag has relationships around the world, in both the steel and ag industry, to source the best raw materials.
The result is a part built to the same standard without the overhead of a dealer network.
HOW AFTERMARKET PARTS KEEP OEMS ACCOUNTABLE
When farmers have access to quality aftermarket parts at lower prices, OEM manufacturers can no longer set replacement part costs without competition. Companies like Kooima Ag who offer USA-made parts below OEM pricing create a market ceiling that holds big-name manufacturers accountable. The result is a fairer market for every farmer, whether they buy aftermarket or not.
AT THE END OF THE DAY
Choosing between OEM and aftermarket parts comes down to one question: what are you actually paying for?
With OEM, part of that price covers dealer infrastructure, distribution layers, and brand premium — not necessarily better materials or engineering. With a quality manufacturer like Kooima Ag, you pay for the part itself: engineered to perform, tested in the field, and priced without the markup.
FREQUENTLY ASKED QUESTIONS
Kooima Ag aftermarket parts are priced a significant discount compared to OEM part — a direct result of eliminating dealer markups and middlemen from the supply chain.
Kooima Ag engineers deconstruct and analyze OEM parts, then re-engineer them for equivalent or improved performance. Parts are validated through metallurgical analysis, wear-pattern testing, and real-world field trials.
Kooima Ag produces both OEM-equivalent replacement parts and a proprietary line of high-performance aftermarket components for agricultural equipment. Look for parts marked “HP” (for high performance) or items coated with our proprietary “Koyma Klad” coatings for the higher performance option.
When purchased from a reputable manufacturer with documented engineering and testing processes, aftermarket parts are a reliable alternative to OEM. Quality varies by supplier. Look for manufacturers with in-house engineering, material testing, and field validation programs. Always check for compatibility with your OEM and your OEM warranty.
